[In the accompanyingidrawings. only suchdetails of mechanism as relate particularly to the'rolls and their driving mechanism are shown and these are illustrated in conjunction'fwith diagrammatic views to illustrate the operation and thus avoid the complications of showing the details of a complete instrument.

. In the accompanying drawings, the music- 'rolls 1, 2 are mounted in suitable'bearings supports 3, 4, which, in turn are mounted upon'a suitable base These rolls 1, 2 are located on opposite. sides oi a trackerTboa-rd in one direction or the other depending upon which. of the rolls 1, 2 is actingas the driving roll. The roll 2 is permanently arranged in its supports, while the rolllmay be re moved. The roll- 1 maybe removed from its bearing 6 by forcing itendwise against its. driving shaft 7, Sand shaft being nor T, over which the music sheet S is-drawn i mally pressed inward by aspring.8 and having at its inner end a slot 9 which will engage a pin- 10 formed on the spindle pro jectingfrom theend of the roll." This pro- .vides for ready. insertion and removal of the music-roll and its music sheet.

' The non-removable roll 2 has an extended shaft "11 which. projects throu h a clutch member-12 into the hub 13 of-a riving gear 14:. This gear jl has a clutch member 15 arranged to engage the clutch member 12 and the two clutch members are normally separated by'a' spring 16 arranged upon the shaft 11 and within the hub of the gear.

An identical a-rrangement, is provided for the gearlf? which has aclutch member 18 adaptedto-be engaged with and disengaged from a clutch member 19 which is suitably connected with the driving shaft 7 of the roll-1. The two driving gears 14;, 17 which act respectively as driving gears for the rolls 2 and 1 are interconnected by a. main driving pinion 20 and an intermediate pinion 21. The main drivin pini" 20 is connectedwith the main drivmg shaft 22 which is driven by the windsmotor M. This motor 1s 1n turn actuated by the mainsuctiombelated by a motor M;

It will be noted from the above that the driving motorfM through itsshaft 22, pin;- ions 20 and 21 will constantly drive the gears 14, 17 in opposite directions and that the gears, pinions and driving connections are always in mesh. The driving effect of either of'the gears 14, 17 will be imparted to the respective rolls 2, 1',.dependent upon which of the respective clutch devices are in engagement so that as one roll acts as a lows X, which is herein illustrated as actu V driving roll to dr aw the music-sheet S over v the music-sheet S-may be positively drawn in either direction across the trackerboard '1. a

When expanded, these bellows And 3 release the clutches of the respective gears 14, 17 and when subjected to exhaust, they cause an engagement of said-clutches. :Itwill be noted that the bellows A. has a projecting- .finger 23 whichever-lies; the outer end of the hub 13 of thegear 14 and the bellows B of the hub 25 of the gear 17.

There are also formed in the movable block 'Q'Z channels 35, 36 which noon to the atmosphere and which connect either the port'31 or the port 32 of the stationary block with theatmosphere.

From the above, it will be seen tnat the sheet will be continuously moved either in one direction or the other at the same speed and without appreciable pause. Of course, it is to be understood that the driving mechanisms for the rolls as above described may he used in conjunction with any type of machine and with any type of.

The valve mechanism V has a channel it-which is connected with one set of tracker-openings t ands channel connected with the second set of tracker'-open in'gst. It is also'provided with passages 46, 47, both of, which connect through passages 48 with ducts 49 which correspond in number with the player pneumatics and the tracker-openings and arc-arranged to release the valves of the player pncmnatics. The passages a l, 46 and the passages 45,, 47 are controlled respectively by diaphragn'ls 50, 51 and these diaphragms are actuated by connectionflto the main suction through the bellows A and B to which they are con nected'by ducts 52, As illustrated in. Fig. 6;thedu'ct 53 connecting with the hell lows subjects the diaphragm 51- to the suction of the main bellows and raises said diaphragm so that the ducts t are connected with the player pneumatics through a series of tubes In the drawings, there is but a single pneumatic illustrated, with a sheet.
